Flexible electronics are increasingly feasible with the development of semi organic displays and optical fiber circuits. Thin flexible polymer batteries are currently being developed; I have seen working prototypes.
I don't want to carry two things if I can carry one.
The wallet phone mouthpiece is on one flap and the earpiece on another. There is a little catch that keeps the money from falling out while you talk.
If you forget where you put your wallet, you could call it with another phone or use GPS tracking.
You might say that the wallet phone would be as big as the wallet plus the phone, that the idea is roughly equivalent to taping one to the other. I agree, I wouldn't want one if it were too big.

On the positive side, I could in fact put my money where my mouth is, but the downside is that I would very likely see an huge increase in my cell phone fees because, as we all know, money talks...
So, [ ] from me.-- Canuck, Feb 22 2011 I wouldn't want to routinely put something near my face that sits on my left cheek all day. Neither bone nor bun...-- kevinthenerd, May 29 2011 You guys must have dirty arses!-- pocmloc, May 29 2011 random, halfbakery
